To all whom t may concern:

Be it known that I, kCHARLES D. BROU- Ynrrn, ra citizen of the United States, residing at Topeka, in theA county of Shawnee and State'of Kansas, have invented certain new and useful lmprovements in Spring Bottoms;A and I do declare the vfollowing to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to spring bottoms in which coil springs are employed to provide the necessary cushion. The primary object of the invention is to provide novel braces-lor tying-in wires which will maintain the springs in proper spaced relation insuch a manner as to prevent sagging. The tyingin wires provide flexible connections between the springs while at the same time permitting sufficient resiliency topermit the springs to resume their original position when the load on the spring is removed. lt is an important feature of my invention, that by its construction the necessity for having outside frames is eliminated; and it is also an important feature of the invention that a level upper surface of the spring bottom is insured.vv The tying-in wires not. only Vbrace thek spring but they maintain them in proper spaced relation and in the embodiment of the invention selected 4for illustrative purposes the `tying-in wires are provided ywithfbroad bearings for engaging the spring coils so that a certain amount of rigidity is provided for the assembled structure. The tying-in wires are so constructed that a simple method of assembly is provided and liability of accidental displacement is eliminated. l

In the manufacture of spring bottoms the cost of production is an important feature because competition is-'keen yand in order to becommercially successful a spring bottom must be manufactured inexpensively and yet be capable of extended use without breaking down. All of these features'have been taken into consideration in the development of my invention and in practice I havefound that parts of the spring bottom can be readily assembled in an expeditions so that the ultimate `cost of the spring bottom will be reduced to a minimum. The novel details of construction of the invention will be thoroughly understood and appreciated by reference to the following description in connection with the accompanying drawings, in which- Fig. l is a fragmentary perspective View of a spring bottom constructed in. accordance with my invention. y

Referring new to the drawings by numerals of reference;

l designates the top frame and 2 the bot-,

tom frame of a spring bottom. The `bottom frame is shown as provided with longitudinal stay wires 3 and transverse complementary stay wires 4, at the intersections of which are seated the coil springs 5. The

`outer coil springs are fastened tothe frame l by wire .wrappings ti andthe intermediate rows of springs are fastened one to the other and to the outer coilv springs by tying-in wires lone of. which is illustrated in Fig. 2.

The tying-in wire illustrated in Fig. 2 consists of al strand 7 -bent near one end to form an offset portion' 8 which constitutes a spring seat in that itrests upon the upper edge of vthe top lconvo'lute of the spring to which it is secured. YOne endofthestrand 7 is ,bent back upon'itself to form .a hook 9 and intermediate the hook and the spring seat is a bent olf-set openv loop 10 4to be engaged by a hookjon a complementary tyingin wire. l At the end ofthe strand 7 distant from the hook 9 is a coil 1l terminating in a right angular projecting transverse arm l2 bent downwardly to form a notch or loop receiving seat 13 and terminating in a transverse spring engaging hook 14 'which is adapted, to engage a loop l() on a complementary tying-in wire and to engage over the top .convolute of one of the springs.

The complementary tying-in wire-s are alternately right and lett, that is the hooked portion of lone wire Yfor connecting two complementary springs is disposed in one direction, whereas the complementary tying-in wire is disposed in an opposite direction and two complementary tying-in wires are oil-set one with respect to the other' and for the purpose of description it will be assumed that the left of the spring is across the sheet ot drawings, that is the left ot the spring bot4 tom will be assumed from left to right. The end tying-in wires are somewhat shorter thanv the intermediate ones, one being indicated at 15, Figure 1 lwith a hooked po. tion 16 engaging the ii'an'ic 1. rEhe strand 15 is vfastened tov the top convolute ot one ot the end springs and it is provided with an intermediate loop 1) extending under the top convolute of the spring which it engages, its outer endbeing fastened by a hook tothe spring.A In applying the next tying-in wire such as is shown inL Fig. 2 the coil portion 11 is cause-d to engage the top convolute ot'one of the springs 5 in the manner shown in Fig. 4. The strand 7 is then turned in the direction indicated by the arrow 17 and at the Sametime the strand is tilted in the direction of the arrow 18 so as to wind the coil 11 about the top convolute ot the spring a as shown in Fig. 5. rThe spring containing the tying-in wire 15 is then tilted as is also the spring carrying the tying-in wire 7 so that the hooked portion 14 can engage through the loop 10 and over the top -convolute of the spring as shown in 5 so that an interlock is made as shown in Eig. 3.` The opposite end of the strand 7 now engages the left aligning spring ot the longitudinal row in which the strand is tastened and the loop l0 is slipped under the top convolute of the second spring in the longitudinal row with the spring seat 8 resting' on top ot the spring and the hook 'tastened to the spring by slightly closing the hook to 'tornav a secure loop. New two transverse springs and tw-o longitudinal springs (three inr all) are fastened together.

Now the operator takes a lett hand tyingin member and winds it about the top convolute of the second spring in the second longitudinal row securing it according to the same illustration in Figs. 4 and 5, causing the hook 14 to enga-ge under the loop 1() and over the top convolute oit the second spring in the first longitudinal row to Jforni an. interlock. The opposite end of the strand-'just applied being fastened to the third spring in the iirst longitudinal row in the same manner as described in thelirststrand 7 and4 these interlocking arrangements being continued throughout the rest of the spring so when two Alongitudinal rows of springs 'are secured together the vsame process 1s repeated with respect to the second and third rows and so on until all o't the springs are tied in so that there can be practically no sidewise move-ment of the spring yet the spring bottom will possess a marked vertical resiliency permitting free tom are depressedv there will be a slight "t pivotable or sliding contact between the end ot the loop 10 and the loop receiving notch 13 so as to provide the necessary flexibility. The coil portions 11 will have a very slight play between the springs in each longitudinal' row but while this slight play is permitted both longitudinally and transversely the eiiectiv'e rigidity of the structure will not be sacriiiced.
